In recent years I have used the respective Business Class product longhaul on LH
.on A332, A333, A343, A346, B763 and B772.
Of these, DL
's B777-200LR (77L) with their Full Flat Sleeper Suites
was the newest installation I experienced.
None of these featured anything that came close to "Individual Climate Control".
